Hi, Marie!
I ordered our
discounted Disney PhotoPass+ around the time I started making our Advanced Dining Reservations (180 days in advance) just to be sure that I had everything on my checklist completed.
Much like other online orders with Walt Disney World (i.e. online purchase of an Annual Pass), the item that you'll receive in the mail will be a voucher which you'll then hand to a Cast Member once you are in WDW. For the PhotoPass+, you can do so at any photo viewing station in the parks and Downtown Disney. At that time, your PhotoPass+ will be activated, with the Cast Member attaching the dates of your stay to the card. It's very simple!
No worries about getting it this soon, Marie. Besides, with the beautiful stock photos on the CD that will be sent with your voucher, you'll be able to get yourselves excited for your big trip!
Happy planning, Marie! Be sure to send us more questions as you think of them; we love to help!
